Merchant-Ship-Photos exists for the exchange of merchant ship photographs of all eras.
Per Yahoo policy, you must own the copyright of, or have permission to reproduce, any photos you submit. If you took the photo, by definition and international law you own its copyright, unless taking the photo under a legal condition where the rights go to another entity, e.g. a USN official photograph taken by a USN photographer for non-personal reasons. USN official photos may be reproduced copyright-free as long as they are identified as USN official photos. Paintings of merchant ships of the pre-photography era are also allowed. Photos of unknown ships may also be submitted to identify. Sister group: http://groups.yahoo.com/group/warship-photos
Yahoo has restored archiving attachments but ONLY by having individual emails show only thumbnails, requiring a member to download the full size file from the website. This group has voted that they prefer to receive full size pictures in email and NOT have them archived. If you are not set to receive individual emails, you will not receive the pictures. HOWEVER: Most members of this group also crosspost to the group http://groups.yahoo.com/group/shiplovers/ which DOES archive the images. If you prefer to receive digests or individual messages with thumbnail images and retrieve them from a group's Yahoo web page at your leisure, consider joining the shiplovers group.
